在这项研究中，从产后第14天到第35天，对一窝幼鼠及其母亲进行了持续视频监控，以描述在此期间发生的行为变化。在开始摄入固体食物之前（第18天），幼仔的大部分活动时间都用于哺乳。在第18 - 26天期间，喂食、饮水、梳理毛发和打闹迅速成为频繁的日常活动，而哺乳逐渐开始下降。到第28天，幼仔相对于体重的食物和水摄入量以及分配给新行为的时间达到渐近线。然而，幼仔继续交配直至第34天。这些结果表明：（1）从牛奶到固体食物的转变是一系列行为变化的结果，（2）这些行为变化具有明显的时间特征;以及（3）第14天到第34天之间的发展时期可以分为三个阶段。除了观察任何形式的生命从早期的原生质简单发展到复杂的成熟，有坚实的科学理由，心理学有很多希望从分钟和准确的记录，所有物种的年轻动物的发展时期（小，1899年）。
In this study, litters of rat pups and their mothers were continuously video‐monitored from Day 14 to Day 35 postpartum in order to describe the behavioral changes that occur during that period. Prior to the onset of solid food intake (Day 18), pups spent most of their active time suckling. During Days 18 to 26, feeding, drinking, grooming, and play‐fighting rapidly became frequent daily activities, while suckling gradually began to decline. By Day 28, pups' food and water intake relative to body weight and time allocated to the new behaviors reached asymptote. Pups nevertheless continued to suckle until Day 34. These results suggest that (1) the transition from milk to solid food is embedded in a multitude of behavioral changes; (2) these behavioral changes have distinct temporal characteristics; and (3) the developmental period between Days 14 and 34 can be divided into three phases.Apart from the fascination and the self education of watching the developing of any form of life from its early protoplasmic simplicity into that complex maturity, there is solid scientific reason that Psychology has much to hope from minute and accurate records of the developmental periods of young animals of all species (Small, 1899).
